ter in all the figures.

A, A are the 'frame pieces on which the working arts are mounted.

B is a vertical shaft driven from the pulley B and provided with the gear B which meshes with the gear B on the shaft 13. B is a somewhat larger gear. wheel on the shaft B meshing with a small pinion B on the sleeve B which is mounted on the shaft B.

O, C are spouts which are mounted on ad carried by the sleeve. v 1 I C is a supply chute which opens into the central ring C whence the spouts radiate downwardly and outwardly.

D is a cover or casing for the operating parts.

E is a cone-shaped shield supported on the collar E through which the shaft passes and it rests upon the cup E in the central framepiece or hub E At the outer edge of the cone is the annular floor E". A similar annulus F is placed above the floor. It serves as the roof-of the annular chamber into which the spouts open. Itis continuouswith the cone-shaped piece F and thus the parts which form the annular chamber are rotated with the shaft by means of the collar E fixed thereon. The spouts are rotated in the same direction, but because of the different relation between the gear B and B and the gear B? and B the spouts travel slightly faster than the annular chamber.

In the bottom of the covering D and between its outer wall and the wall of. the ring G is a water chamber G with a drip pipe G The ring G together with the hoppered Like parts are indicated bythe same let portion G constitutes a dried material receptacle. J is the top, J the inclined walls and J 2 a pipe which leads from the movable receptacle which is mountedupon the vertical pivot rod J which passes through the edge of the annular top F and the edge of the annular bottom E so that the water receptacle is pivotally mounted and supported between the top and bottom. K is a perforated screen which closes the remaining side of the receptacle. The pivot rod J projects downwardly from the bottom and has secured thereto a cross-bar L from which pro ,jects an arm L carrying a weight L From the two ends of the crossbar L passes chains L L to the two ends of a similar bar L which is secured to the elbow lever L which passes up through the bottom E The other end of this elbow lever projects into the path of a roller M on a tripping arm M which projects from the spout C in the direction of travel.

These several parts can, of course, be greatly varied without departing from the spirit of my invention and I wish my drawings to be taken, as in a sense diagrammatic and intended to illustrate the generalideas of this invention without confining myself to the particular device or structure shown.

The use and operation of my invention are as follows: Assuming that the parts are constructed substantially as shown, the machine set in operation, there will be an annular material compartment between the floor E and the roof F and the series of screens which form the front side of the several water receptacles. In operation this material receptacle and this series of water receptacles will be rotated in a given direction, while the spouts will be rotated in the same direction but a little faster. The actual speed and the relative speed can be anything desired or suitable for any given material. Obviously if the material to be dried is now fed into the chute, it would ascend into the spouts and will pass through them into the annular receptacle chamber, and since the spouts travel a little more rapidly than the receptacle or channel, the

When the arm N of a given spout pro-' ceeds until its roller strikes the upper end of the elbow lever l\ the latter will be rotated on its Vertical axis and thus the crossbar L will be rotated and so also the crossbar L. This will tilt the arm L and the weight L to one side and at the same time tilt the water receptacle associated therewith until the screen K is placed at an angle to the tangent of the circle of rotation. This will also separate the Otherwise closely approximate vertical edges of the water receptacles and will permit the dried material on the particular screen section in question to be discharged by centrifugal force-against the ring G and downinto a hopper G As soon as the arm and its roller escapes from contact with the elbow le"er the weight L will responsive to centrifugal action resume the position shown in Fig. 5 and restore the parts to their position shown in the drawings. Immediately after this action the spout which discharges in the direction of travel will fill said receptacle with moist material and thus the action will proceed continuously. i

I claim:

1. In a drier the combination of a material supplying device with a drying compartment to which it delivers and means for rotating them differentially in the same direction, said drying compartment having a series of separately mounted screen sections and means for successively tilting them responsive' to such difi'erential motion to discharge the dried material from them by centrifugal force, a funnel shaped liquid compartment immediately behind and closed by the screen. and mounted for rotation in unison with the screen.
